New Updated Java SDK Released!

Hello Sinch Developer Community!

The topic for today is our SDK support for Java. We want to provide a closer look at our philosophy behind the design, how we’re tailoring this to Java developers, and to provide a space for questions and comments.

When we started out with the design of the new SDK components, we wanted to ensure we were building them with the specific language first and foremost.  After that, our focus was to keep the design simple for users that only want to leverage specific API calls they use while ensuring customizability and future-proof access to other parts of our infrastructure.

Within each SDK we’ve added common capabilities to further streamline the interaction with our platform:

  • We have provided a simple HTTP component for ease of use.
  • We have provided automated token management/refresh code, so developers can use the system without micromanaging their authorization/authentication.
  • We have provided webhook helpers to serialize/deserialize in communication with our servers and validate webhook authentication.

Another goal of ours while designing this new Java SDK was to mimic our REST APIs as much as possible, while still providing a Java developer experience.  We also use IDE type hints which, along with the REST API specification, allows the user to perform most API interactions without the need to use reference documentation.  With all these common items, we hope to build out consistent frameworks with functionality all users will commonly leverage.


Discoverability is one of the key components of great DX, hence Java SDK namespaces are small and specific yet descriptive. For example:
var response = SinchClient
               .numbers()

               .available()
               .list(AvailableNumberListAllRequestParameters.builder()
                         .setType(NumberType.MOBILE)
                         .setRegionCode("US")
                         .build());

The main client class organizes the Sinch product portfolio (called domains within SDK) and its features into hierarchy that produces an API that is easy to read and discover.

Currently, we support Java 8 and later LTS versions. Language versions will be supported until EOL.

Two 3rd party libraries are used by the Java SDK, the HTTP Apache client and Jackson.. Serialization/deserialization are managed by the SDK for webhooks integration.

For now, SMS, Numbers, Verification and Voice APIs are supported, with other public Sinch APIs to be added soon. We also provide online Javadocs for additional information.
